8xMicrophones on 4x1-bit ports possible?
Posted: Wed May 17, 2023 10:28 am
Hi,
We are currently working on a project where we want to utilize the microphone array library to simultaneously read data from eight microphones. However, we suspect that there might have been an error in our PCB design. Instead of connecting all the PDM data channels to a single 8-bit port as recommended by the microphone array library, we inadvertently connected them to four separate 1-bit ports. Furthermore, we paired two microphones (left and right) together on one of these 1-bit ports.
Considering this deviation from the recommended configuration, we are wondering if it is still possible to successfully read out the data from the microphones using multiple 1-bit ports.
We would greatly appreciate any insights or advice you can provide. Thank you in advance for your responses.
